BOTTLE-CAP REMOVER.

Specification of Letters Patent. Patented June 25, 1918.

Application flied October 22, 1917. Serial No. 197,930.

To all whom it may concern:

Be it known that I, LAFAYETTE E. Oscooo, a citizen of the United States,residing at Endeavor, in the county of Forest, State of Pennsylvania,have invented a new and useful Bottle-Cap Remover; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The present invention relates to a bottle cap remover, and has for itsobject to provide a device which can be permanently mounted upon abottle neck and embodies novel features of construction whereby acrimped cap can be easily and quickly re moved at, any time without thenecessity of providing a separate implementv for that purpose.

Further objects of the invention are to provide a bottle cap removerwhich is comparatively simple and inexpensive in its construction, whichcan be easily applied to a bottle neck, which will not interfere withusing the conventional crimped caps or prevent the bottle from beinghandled and packed in the usual manner, and which can be manuallymanipulated at any time to unseat and remove the crimped cap when it isdesired to open the bottle and remove the contents thereof.

With these and other objects in view, the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which Figure 1 is aside elevation of a bottle neck provided with a cap remover constructedin accordance with the invention, the device being shown in inoperativeposition with a crimped cap closing the mouth of the bottle.

Fig. 2 is a similar view showing the osition assumed by the device afterit has een manipulated to unseat and remove the crimped cap.

Fig. 3 is a vertical sectional view through the bottle neck and capremoving device.

Fig. 4 is a plan view of the cap unseating Referring to the drawings,which illustrate one possible embodiment of the invention, the numeral 1designates a bottle neck which has the usual exterior rib 2 at the upperend thereof for engagement with a conventional crimped cap 3.Immediately under the rib 2 the bottle neck is provided with an exteriorannular groove 4, the lower edge-of the groove being roughened orserrated, as indicated at 5. A non-rotatable or fixed cam ring 6 isfitted in the groove 4:, the lower edge of the said ring being formedwith serrations which corresepond to and engage the serrations 5 of thegroove, while the upper edge of the ring is formed with a cam surface 6.Arranged immediately above the non-rotatable cam ring 6 is a rotatablering 7 which is also adapted to have a longitudinal or up and downmovement upon the bottle neck. This rotatable ring 7 is formed with anoutwardly projecting annular flange 7* which is milled or roughened soas to be firmly gripped by the fingers, and has a loweincam edge 8 whichengages and corresponds to the upper cam edge 6 of the ring 6. A thirdring 9 is preferably arranged above the rotatable ring 7, said ringbeing adapted to engage the lower edge of the crimped cap 3. Otherwise,the uneven edge of the crimped cap might offer resistance to therotation of the cam ring and make it diflicult at times to manipulatethe cap removing device. The upper edge of the ring 9 is preferablybeveled, as indicated at 9, so that the ring can move upwardly over thebase of the rib 2 of the bottle neck a sufficient amount to insurecomplete-unseating of the crimped cap.

The three rings 6, i and 9 are to be formed of some non-corrosivematerial, such as aluminum or, heavily galvanized iron, said rings beingheld permanently in position within the groove 2 of the bottle neck sothat there is no possibility of their being lost or misplaced. Theseveral rings are therefrom, although after being placed in positionthey are bent to close the slits 10 .t

and bring the sides thereof closely together.

The two opposed cam surfaces of the nonrotatable ring 6 and rotatablering 7 cooperate with each other to provide for forcibly lifting thering 7 when it is rotated in one direction, thereby causing the upperring 9 to force the crimped cap 3 from its seat and remove it from thebottle. On the other hand, when the rotatable ring 7 is turned in theopposite direction the ring can be lowered upon the bottle neck and theupper ring 9 moved away from the rib 2 so that there will be nointerference with the crimped cap 3. When the rotatable ring 7 is inthis latter position, as indicated by Figsl and 3 of the drawing, thecap 3 can be applied to the mouth of the bottle in the usual manner andwill remain firmly in position thereon. When it is desired to remove thecrimped cap it is merely necessary to grasp the milled flange 7 of thering 7 and rotate it in the proper direction for bringing the camsurfaces into action and forcibly lifting the ring 7 as indicated byFig. 2.

' I claim as new and desire to secure by Letters Patent, is I 1. Thecombination with a bottle neck and a crimped cap applied to the mouththereof,

of a non-rotatable ring mountedupon the bottle neck and formed with acam. edge,

and a rotatable ring mounted upon the bottle I neck between thenon-rotatabl e-ring and the cap and arranged to have a longitudinalmovement upon the neck, said rotatable ring being formed with a cam edgearranged for cooperation with the cam edge of'the nonrotatable ring toforce the rotatable ring toward the cap to unseat the same when the ringis rotated.

2. The combination with a bottle neck and a crimped cap applied to themouth thereof, of a non-rotatable ring applied to'the bottle neck andhaving a cam edge,v a rotatable ring having acam edge arranged in006perative relation 'to the cam edge of the nonrotatable ring, and acap engaging ring interposed between the rotatable ring and the cap, thecap engaging ring and rotatable ring being mounted to have alongitudinal movement upon the bottle neck so that by turning the rotaryring to bring the cam surfaces into operative relation the cap can beforcibly unseated-from position.

3. The combination with a bottle neck having an annular groove therein,a crimped cap applied to the mouth thereof, of a nonrotatable ringpermanently seated in the a lower end of the groove and having an uppercam edge, and a rotatable ring loose in the groove above thenon-rotatable ring, said rotatable ring being formed with a fingerengaging flange and with a lower cam edge so that by rotating the ringand bringing the cam edges of the two rings into coopso erative relationthe rotatable ring can be moved longitudinally upon the. bottle necktoward the cap to unseat the same.

4a The combination with a bottle neck hav- 7 ing an exterior groovetherein, said groove being formed with a serrated lower edge, and acrimped cap applied to the mouth of the'bottle neck, of a non-rotatablering seated in the lower end of the groove and having an upper cam. edgeand a lower serrated edge for engagement with the serrated edge of thegroove, and a rotatable ring loosely mounted. within the groove abovethe nonrotatable ring, said rotatable ring being provided with a fingerengaging flange and a. lower cam edge so that by rotating the ring tobring the cam edges of the two rings into cooperativerelation therotatable ring can be moved longitudinally upon the bottle neck toforcibly unseat the crimped cap ing an annular groove in the exteriorHaving thus descrlbedthe invention, what thereof, the lower edge of thegroove being serrated, and a cap-applied to the mouth of we a lower camedge, and an upper cap removing ring interposed between the intermediatering and the cap, rotation of the intermediate ring to bring thebefore'mentioned cam edges into cooperative relation serving to move therotatable ring and cap removing 'ring longitudinally upon the bottleneck to forcibly unseat the cap from position.
